Sempervivum plant named ‘Belsemmag2’

ABSTRACT

A new cultivar of Sempervivum plant named ‘Belsemmag2’ characterized by its foliage that is dark burgundy red to nearly black with bright red new leaves in spring, turning to soft rose-red with green accents in summer, and red-purple and grey-green in autumn and winter, its strong root system, and its suitability for growing outdoors year around.

Botanical classification: Sempervivum marmoreum X Sempervivum tectorum.

Variety Denomination: ‘Belsemmag2’.

CROSS REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant VarietyOffice (CPVO) Application No. 2022/2726 filed on Nov. 30, 2022, under 35U.S.C. 119(f), the entire contents of which is incorporated by referenceherein. The information for the plant breeders' rights application wasreceived directly from the Inventor.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofSempervivum of hybrid origin and will be referred to hereinafter by itscultivar name, ‘Belsemmag2’. The new cultivar of Sempervivum is a hardysucculent perennial grown for use as a landscape and container plant.

The new cultivar resulted from a controlled breeding program conductedby the Inventor in Westerlo, Belgium. The Inventor made a cross in 2011between an unnamed and unpatented plant of Sempervivum marmoreum as thefemale parent and an unnamed and unpatented plant of Sempervivumtectorum in the Inventor's breeding program as the male parent.‘Belsemmag2’ was selected as a single unique plant in 2013 from theresulting seedlings of the above cross.

Asexual propagation of the new cultivar was first accomplished by theInventor by cuttings in 2013 in Westerlo, Belgium. Asexual propagationby cuttings and offshoots has determined the characteristics to bestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe the characteristics of the new cultivar. These attributes incombination distinguish ‘Belsemmag2’ as a unique cultivar ofSempervivum.

-   -   1. ‘Belsemmag2’ exhibits foliage that is dark burgundy red to        nearly black with bright red new leaves in spring, turning to        soft rose-red with green accents in summer, and red-purple and        grey-green in autumn and winter.    -   2. ‘Belsemmag2’ exhibits a compact, well-branched rosette-shaped        growth habit with many rosettes.    -   3. ‘Belsemmag2’ exhibits a strong root system.    -   4. ‘Belsemmag2’ exhibits suitability for growing outdoors year        around.

The female parent of ‘Belsemmag2’ differs from ‘Belsemmag2’ in havingfoliage that is dull red-brown in color in spring and green in summer.The male parent of ‘Belsemmag2’ differs from ‘Belsemmag2’ in havingfoliage that is lighter in color; very pale red in color with lightyellowish green accents. ‘Belsemmag2’ can be most closely compared tothe Sempervivum cultivars ‘Belsemred1’ (U.S. Plant Pat. No. 31,919) and‘Bedivere’ (not patented). ‘Belsemred1’ is similar to ‘Belsemmag2’ ingrowth habit and rosette size. ‘Belsemred1’ differs from ‘Belsemmag2’ inhaving foliage that changes less with the seasons; red to red-purple inspring to autumn and turning brown-purple in winter and lacks greencoloration and more numerous and longer foliage hairs. ‘Bedivere’ issimilar to ‘Belsemmag2’ in rosette size. ‘Bedivere’ differs from‘Belsemmag2’ in having foliage that is pale orange-red with faded lightgreen in color.
